276 FISHES. 



ceous; D. I, 7; A. I, 7; lat. 1. 46; L. 2. Ohio Valley 

 to Upper Missouri. Known at sight, as it resembles 

 nothing else. 



2. P. milesii, Cope. MILES MINNOW. Snout longer; 

 eye larger; mouth larger; color paler, usually a blackish 

 lateral stripe; D. I, 8; A. I, 7; lat. 1. 40. Mich, to Ky. 

 (JP. agassizii, Cope.) 



4. HYBORHYNCHUS, Agassiz. BLUNT-NOSED MINNOWS. 



1. H. notatus, (Raf.) Ag. BLUNT-NOSED MINNOW. 

 Brownish or bluish, a dusky shade along sides sometimes 

 forming a caudal spot; a distinct black spot on middle 

 of front rays of dorsal; head short; snout in spring 

 males with disproportionately large tubercles, usually 

 fourteen in all; a distinct barbel at each angle of the 

 mouth; scales in front of dorsal small and crowded; 

 D. I, 8; A. I, 7; lat, 1. 45; L. 3 to 4. N. Y. to Term., 

 Wis., and Mo.; very abundant in the Ohio Valley. (H. 

 superciliosus, Cope. This form, said to be distinguished 

 from the true &quot; notatus &quot; by the presence of the barbel, 

 is the only one I have yet seen. Specimens from 

 Rafinesque s original locality possess the barbel.)

1. H. nuchalis, Ag. BLUNT- JAWED MINNOW. Smaller 

 and more dusky than the next; eye small, shorter than 

 snout, 4 to 4J in head; depth 4- in length, about equal 

 to length of head; scales in front of dorsal very small 

 and crowded; D. I, 8; A. I, 8; lat. 1.38; L. 2|. Ohio 

 Valley and W. This and the next may be readily known 

 from the Hybopxes, which they strongly resemble exter 

 nally, by the peculiarities of the intestines.
